Cancel Subscription Checkout

PATCH/subscription-checkouts/:id/cancel

Description

Cancel a pending subscription checkout intent before the customer signs. Use this when the customer abandons the checkout, the order is voided merchant-side, or the intent should no longer be honored.

This endpoint cancels the intent. To cancel an active on-chain subscription, use POST /subscriptions/:id/cancel instead.

⚠️

Cancelling a pending intent does NOT abort an in-flight on-chain subscribeAndCharge transaction. If the customer’s transaction is in the mempool when you cancel and confirms after, the indexer flips the intent back to completed and you receive a subscription_checkout.completed webhook. Merchants must handle this case. The latest webhook is authoritative.

Cancel by current state

Current `status`	Response	Notes
`pending`	`200` — `status: cancelled`	Fires `subscription_checkout.cancelled` webhook.
`cancelled`	`200` — existing record	Idempotent no-op. Webhook does not re-fire.
`completed`	`400 invalid_request`	Cancel the materialized subscription via `POST /subscriptions/:id/cancel`.
`expired`	`400 invalid_request`	Intent has expired; nothing to cancel.

Errors

Status	Code	Description
400	`invalid_request`	The intent can’t be cancelled because its status is `completed` or `expired`.
404	`not_found`	Intent ID does not exist.
403	`forbidden`	Intent belongs to another merchant.

Webhook Fired

subscription_checkout.cancelled — fires once on the pending → cancelled transition. Re-cancels do not re-fire.
